In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
In the embodiment of the present invention, by user equipment（User Equipment,UE）The cell of current home is referred to as " servicing small
Area ".
Embodiment one
The present embodiment provides a kind of method for transmitting upward signal, and the method for the transmission upward signal is applied to radio communication
Network, COMP can be carried out by being particularly suitable for use in（Coordinated Multi-point Transission/reception are more
Point joint transmitting/reception）In the network of operation.The method for performing the transmission upward signal of the present embodiment can be the up letter of transmission
Number device, the device of the transmission upward signal can be integrated in the serving cell network element of serving cell, the serving cell net
Member can be specifically base station.
As shown in Figure 1A, be according to the present embodiment transmission upward signal method schematic flow sheet.
Step 101, the information for the Internet resources that scheduling cell is sent is received, scheduling cell is the service that user equipment belongs to
The adjacent area of cell.
The cell that user equipment belongs to is referred to as " serving cell " in the present embodiment, the network side equipment in the serving cell
Referred to as " serving cell network element ".Dispatch the adjacent area that cell is serving cell.It can include using in the information of the Internet resources
The mark of family equipment.
Step 102, the information of Internet resources is sent to user equipment, so that user equipment sends up by Internet resources
Signal.
Transmit the net that the device of upward signal is distributed in the scheduling cell for receiving user equipment transmission for the user equipment
After the information of network resource, just the information of the Internet resources is sent to corresponding user equipment.
User equipment is received after the information of the Internet resources, just according to frequency entrained in the Internet resources distributed
(Hybrid Automatic Repeat Request, mixing is certainly by rate, power, modulation system, transfer resource block message or HARQ
Dynamic repeat requests) information etc., sent by the Internet resources to serving cell network element in upward signal, upward signal and carry use
The business datum of family equipment.
According to the method for the transmission upward signal of the present embodiment, sent out by using the Internet resources of the adjacent area of serving cell
Upward signal is sent, the network burden of serving cell can be mitigated, the patency of user equipment signal transmission is ensured as far as possible.
Alternatively, as shown in Figure 1B, before step 101, in addition to：
Step 111, transmit and believe between the serving cell network element and user equipment that obtain the serving cell of user equipment ownership
Number when the first power attenuation for producing.
The method for the first power attenuation that the device of transmission upward signal obtains serving cell has many kinds, and concrete example can
To be：
Receive DL RSRP that user equipment is sent, by measuring obtained serving cell network element；
According to the DL RSRP of serving cell network element and default serving cell network element downlink reference signal transmission power,
Obtain the first power attenuation produced when transmitting signal between serving cell network element and user equipment.
User equipment can obtain the DL RSRP of serving cell network element by measurement, then by the serving cell network element
DL RSRP are sent to the device of transmission upward signal.The downlink reference signal transmission power of serving cell network element can be advance
It is arranged in a reference table, the downlink reference signal transmission power of serving cell network element and each neighbour can be included in the reference table
The downlink reference signal transmission power of the adjacent area network element in area.When the device of transmission upward signal needs to obtain under each adjacent area network element
During row reference signal transmission power, the reference table is just inquired about, specifically phase can be got by the identification information of each adjacent area network element
The downlink reference signal transmission power answered.The reference table can be stored in serving cell network element, can also individually be stored,
As long as the device of transmission upward signal can be got, for example, the downlink reference signal of oneself is launched into work(by adjacent area network element
Rate is sent to serving cell network element.
In addition, the device of transmission upward signal can obtain the SRS of user equipment by measurement（Sounding
Reference Signal, detection reference signal）Receiving power or DMRS（Demodulation Reference Signal,
Demodulated reference signal) receiving power.Serving cell net is obtained according to SRS receiving power and default SRS transmission power
The first power attenuation for producing when signal is transmitted between member and user equipment, or receiving power according to DMRS and default
DMRS transmission power obtains the first power attenuation produced when transmitting signal between serving cell network element and user equipment.
Power attenuation in each embodiment is specifically this link generation of eating dishes without rice or wine from serving cell network element to user equipment
Power attenuation.
Step 112, when transmitting signal between the adjacent area network element and user equipment that obtain at least one adjacent area of serving cell
The second power attenuation produced.
Wherein, adjacent area network element can be specifically base station.
The mode that the device of transmission upward signal obtains the second power attenuation has many kinds, and the present embodiment is exemplified below：
Mode one：Receive the DL of user equipment is sent adjacent area network element by measuring at least one obtained adjacent area
RSRP；
According to the DL RSRP of adjacent area network element and default adjacent area network element downlink reference signal transmission power, adjacent area is obtained
The second power attenuation produced when transmitting signal between network element and user equipment.
In mode one, the DL RSRP of each adjacent area network element of user equipment measurement serving cell, and it is sent to the up letter of transmission
Number device, by transmission upward signal device search reference table, get each adjacent area network element downlink reference signal transmitting work(
Rate.The difference between the downlink reference signal transmission power of adjacent area network element and the DL RSRP of adjacent area network element is calculated, the difference is
The second power attenuation when adjacent area network element is with user device transmissions signal, i.e., when a certain adjacent area network element is with user device transmissions signal
The second power attenuation be equal to the downlink reference signal transmission power of the adjacent area network element and subtract the DL RSRP of the adjacent area network element.
Mode two：Adjacent area network element of at least one adjacent area network element transmission of serving cell is received by measuring obtained use
The SRS of family equipment receiving power or DMRS receiving power；
Obtained and transmitted between adjacent area network element and user equipment according to SRS receiving power and default SRS transmission power
The second power attenuation produced during signal, or the receiving power according to DMRS and default DMRS transmission power acquisition adjacent area
